Everything you need to make your decision
The Terex Hi-Ranger XT55 is a 55-foot overcenter aerial bucket truck built for electrical distribution maintenance, telecommunications work, and utility operations requiring the maximum reach class before moving to crane-style aerial platforms. 'Overcenter' refers to the boom's ability to articulate past vertical — the upper boom can swing to the other side of the truck, reaching 40 feet of horizontal outreach behind, beside, and in front of the vehicle from a single position. This overcenter capability is critical for working on both sides of a utility pole or reaching across a right-of-way from a single safe parking position. Platform height reaches 55 feet (61 feet of working height) with a 500 lb single-person bucket. The XT55 mounts on a Class 5 or 6 truck chassis. PTO hydraulic drive draws power from the truck engine. Four-point hydraulic outriggers with extendable arms provide a stable base on off-road shoulders and roadside terrain. Terex's Hi-Ranger series has an 80-year service history in the utility industry — the XT-series is the current production line.

Watch the Terex Hi-Ranger XT55 Overcenter Bucket Truck in action — full installation and operation demo.

Aerial bucket trucks use a truck-mounted hydraulic boom and articulating system to position a work bucket at height. The PTO-driven system draws power from the truck engine — boom operation requires the truck engine to be running.

PTO Engagement

Before operating the boom, engage the Power Take-Off (PTO) via the in-cab switch or lever. The PTO connects the truck's transmission output to the hydraulic pump. The truck must be in neutral (auto) or PTO gear (manual) before PTO engagement.

Outrigger Setup

Deploy all four outriggers before raising the boom. Place outrigger pads under each foot on soft or uneven ground. Confirm all four indicator lights show "set" (or physically verify leveling) before raising the boom above horizontal.

Boom Controls

Both platform (bucket) controls and base controls operate the boom. Platform controls replicate all boom functions with the addition of a platform rotation control. The base controls include an emergency override for all boom functions in the event of power loss in the bucket.

Emergency Lowering

A manual hydraulic override at the base of the boom lowers the platform in the event of engine failure or hydraulic system failure. The operator in the bucket should wear a full-body harness with a lanyard connected to the bucket's D-ring anchor at all times.

Note: Set up on level, firm ground whenever possible. If working on a slope or soft ground, use outrigger pads and check the manufacturer's rated operating slope. Exceeding the rated slope with the boom raised is the leading cause of bucket truck tip-overs.

⚙️ Outrigger Interlock

The boom cannot be raised above horizontal unless all four outriggers show confirmed ground contact. An electronic sensor in each outrigger pad signals the control system. A boom raised without full outrigger deployment is the primary cause of tip-overs in aerial truck incidents.

🛡️ Insulation Testing (Class E)

Insulated bucket trucks require annual dielectric testing per ANSI/SIA A92.2. The fiberglass upper boom and bucket are tested to their full rated voltage (40 kV for Class E). A test port on the unit allows in-field testing without removing components.

🔒 Platform Fall Arrest Anchor

A certified D-ring fall arrest anchor is welded into the bucket structure. All operators in the bucket must wear a full-body harness with the lanyard connected to this anchor at all times — OSHA 1910.67 requirement for aerial devices.

🚨 Emergency Lower / Override

A manual hydraulic override at the base of the boom lowers the platform to ground level independently of all electronic controls and truck power. Location and operation are marked clearly on the unit. Test this system at every pre-shift inspection.

How does this compare?

XT55 overcenter vs. standard 55-foot articulating (Altec AA55E): the overcenter design is the critical operational differentiator. A standard articulating boom can reach in front of and beside the truck. An overcenter boom can swing behind the truck — reaching across a road or over an easement from a single position. For utility companies doing both sides of a pole from one setup, the overcenter saves repositioning time on every job. The trade-off: overcenter booms are heavier and the mechanism is more complex to maintain.
